I ELASTIC SUSPENSION DEVICE FOR MOTOR-CARS.

To" all whomit mayconcem:

Be 11; knownthat I, F RANCESGO PAGLIANO,

manufacturer, of Gorso Vittorio Emanuele- No. 37, Turin, Italy, have invented certain new and useful Improvements in Elastic The objects of my invention are to avoidthe rapid change in the molecular structure of the axle, which renders it crystalline and weakens the axle, due to excessive shocks and vibrations, and to riding for the car bod In the drawings, forming-a part of this specification Figure 1, is a. vertical central section throughja portion of a wheel structure, vehicle axle and related parts embodying my invention. Fig. 2, is a cross sectional View on the line 22 of Fig. 1, showing the axle and stud axle inconnection 'with my invention. Fig. 3, is a similar view of Fig. 2, showing the application, of rear wheels of a vehicle or where there is no necessity for providing steering means at this section of the vehicle.

Similar characters refer to similar parts throughout the views: v

In the drawings, 1 designates an axle of the vehicle, carried stationary with the body thereof, having a sleeve P01430112, at its end, which isprovided with a vertically disposed conical bore 3. Adapted to be carried by the axle 1 is a guide rod 4, extending above and below the said sleeve portion 2 and having an enlarged portion 5 to tilt the said conical bore thereof. The rod 4 is held stationary with the axle 1 by means of a pin 6 passing through the enlarged portions 2 and 5 of the axle 1 and rod 4 respectively.

A wheel structure, indicated at 7 is provided with a stud axle 8 which projects from a yoke'9, the end portions of which yoke are formed as threaded split collars 1O having two clamping ears 11 at the split end portions thereof. Connection between the wheel structure, with its stud axle and yoke,

and the axle of the vehicle, through the guide 4, is accomplished by means of threaded caps 12 adaptedto be adjus'tably carried by the threaded collars 10, which form slidcaused by rough road provide for the easy A hicles, the combination of a. dead axle p able supports for the end portions of the giude rod 4.

Interposed betweentlie sleeve portion 2 of the vehicle axle ing of the threaded caps, held securely in an bolts 13, passing through the clamping ears 11, of the. collars 10. One ofpthe bolts -13 may also serve as means for connection of the steering mechanism of the vehicle to the sive shocks through contact with the ends of the rod 4 should the abilityvof the springs be insuflicient to do so. The operation of the device is as follows,- When the vehicle is riding over rough portions of ground, the shocks or vibration is transmitted to the springs A, which reduce the same to a minimum and provide easy riding of the car body. It will be noted that sprin the axle y which construction the rise and fall of the car body is controlled and that a rise of the body above the expansibility of the lower by the compression It will further be seen thatv has sliding bearing at its end portions which construction provides for a firm guiding, in a vertical line, of the movement between the wheel and the vehicle body and that the resistance between the sliding parts, due to the tendency of the vehicle axle to adjusted position by tiedeform the guide laterally, is reduced to a minimum.

In Fig. 3 the invention is shown applied as a connection between the wheel axle and vehicle axle in which two guide rods and sets of compression springs are used, this construction being particularly applicable where it is not desired to steer the vehicle by movement of the wheel with respect to the stationary vehicle axle.

I claim I 1. In elastic suspension devices for veelow said axle, carried by said stud axle and provided with threaded collars having a commonraxis, bearings adjustably earned by said threaded a wheel axle, of a yoke carried by one of said axles and provided with split threaded collars having ears at the split portions thereof, a guide rod carried by the other collars and embracing said rod above and below said dead axle, and springs above an below said sleeve of said dead axle and engaging said bearings, both of said springs being normally under compression and adjustable by said bearings, substantially as and for the purpose set fort 2. In elastic suspension devices for vehicles, the combination with a dead axle and a wheel axle, of a yoke carried byone' of said axles andprovided with threaded coladjustably carried by said said yoke, adapted to emand below its axle, tie

threaded bearings threaded collars of brace said rod above bolts for drawing the said ears of threaded collars together for retaining said bearings in an adjusted position,and springs lars having a common axis, a guide rod carinterposed between said axle carrylng sa1 ried by the other axle projecting above and guide rod, and said bearlngs, and adapted to v 'be adjusted by the latter, substantially as andfor the purpose set forth.

In witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
